Subwoofer: Facing Down or Up?
Has anyone had experience with both up and down facing subwoofer installation in an extended cab truck? Or just one of those positions?
I have to decide if I will mount one or two sub woofers facing up or down. I have a current sealed box facing forward. Sounds great. 8 inch sub. But I want a larger unit, so it has to go up or down. The interior is all out of the rig, so now is the time to design something for a larger sub woofer or two.
Any personal experience on these options as far as sound, vibration, etc. would be appreciated.

Faceing down you might have a deeper sound almost like a Bandpass. So your 8 could sound like a 10. It's a smaller space for the air to move and fill up..08 Z71 Avalanche Mods to date: K&N CAI,Hellwig Swaybars and End Links, Corsa Sport Exhaust, Superchips Programer,IPCW LOF & 3rd brake light and tails, AMI Gas door,Show Hooks and Door locks, Enkei Wheels, with Pirelli tires, StreetScene Bowties, Grant Steering wheel,Muth signal mirrors,SSBC Big Brake kit,Huskyliner Mug gards,Floor mats and Hood shield, McGard Lug nuts and locks, Bedrug, Cervini's Ram Air hood,35watt HID Fog lights, Sylvania bulbs all around ZXE's Highs and Lows, WhiteNight Back up lights,Sirius and HD Radio, SnugTop sitting on deck now Got a Softopper on now,Tempress Boat Hatches....

The closer a wall, floor, seat, etc. are to the face of the subwoofer, the louder it will be. This is due to the fact that the sound waves bounce off of the wall, or whatever it may be, and go throughout the cab in more than one direction. Right now I have a 12" Kicker L7 facing up in my crew cab, and unfortunately I was unaware of this fact before I had the custom box made. I had the sub previously in an S-10 extended cab facing towards the front right behind the drivers seat. From what I recall, the S-10 was nearly twice as loud as it is now. Now mind you the cab was smaller, but the sub would pound right behind my seat compared to my sub now which just goes towards open space.

In the 99-2007 trucks, up firing boxes will allow you to fit bigger subs (deeper), down firing has always seemed to sound better to me.

I've had both up and down in my 2004 extended cab. I prefer the down firing much more than the up firing. The only rattle problems I've had with the down fire is the spare tire tools. Rearranged them a bit and that problem went away. If you want to go bigger, a 12" downfire is about all you'll fit. 10" is a nicer fit but my 12" still hides itself under the seat nicely.

Since you have to have a lip on the side where the woofer is mounted to allow for cone excursion, when pointing it down are you leaving one or two sides with no lip to allow air to move?
